They look like an orange Ricordea yuma. I have many in my tank. They are very hardy, once established, and they are also very aggressive. They will kill most corals they come into contact with. It is very common for the orange yumas to have a purple base, orange tentacle tips, and a green transition band between the two colors.
I'm pretty sure they are not orange ricordia. I have several orange too and these don't look any thing like them. Those colors you see are the actual colors of the mushroom. No blue lights, nothing.
These have far too many colors to be orange yuma. I'm very familiar with those. Plus the price on these isn't orange Yuma price. It's not the bubbled look that I'm really curious about, it's the color combinations and over all duel coloring to triple coloring on the individual bumps.
